A Common Lisp Framework for the Semantic Web
Tom Gillespi - thanks for the QuickLisp and ASDF changes!
OntoLisp uses Quicklisp to load dependencies.
Add the following block to your ~/.sbclrc file or equivalent
or ~/.config/common-lisp/source-registry.conf.
(asdf:initialize-source-registry
'(:source-registry
(:tree #p"/path/to/OntoLisp/")
:inherit-configuration))From a repl you can then run
(ql:quickload :ontolisp)
(owlapi::owlapi-test)
(owl-syntaxes::owl-syntaxes-test)If compilation is trigger on multiple calls to ql:quickload
you can call (asdf:compile-system :ontolisp) which should prevent
the need to compile the system on each load.

OntoLisp (NOSA): A Semantic Web Framework for OWL 2 and OWLlink in Common Lisp
by Michael Wessel
Version 0.9
OntoLisp (NOSA) is a Common Lisp library providing:
- an ontology management framework inspired by the Java OWLAPI (v2.2)
http://owlapi.sourceforge.net/
- OWl 2 parsers for OWL 2 functional and OWL 2 XML syntax
http://www.w3.org/TR/owl2-syntax/
- OWL 2 renderers for OWL 2 functional, OWL 2 XML, and OWL 2 RDF syntax
- an OWLlink implementation
http://www.owllink.org/
featuring the OWLlink XML, OWLlink functional,
and OWLlink S-Exression syntax, as well as a converter for these
different syntaxes.
OntoLisp has been tested with Allegro Common Lisp (ACL) 8.2, Lispworks
(LW) 5.2, and Steel Bank Common Lisp (SBCL) 1.0.40, using Linux and
Mac OS-X.
OntoLisp is under the Lisp Lesser GNU Public License
http://opensource.franz.com/preamble.html
OntoLisp uses the following third-party libraries / files:
- ASDF - Another System Definition Facility by Daniel Barlow et al.
http://common-lisp.net/project/asdf/
as the system definition facility (ontolisp:ontolisp.asd)
- Wilbur2 by Ora Lassila
http://www.lassila.org/
is currently used only for the XML parsing
(soon for RDF as well, when OWL 2 RDF support will be added in a
future version)
I have made some changes to Wilbur2, please consult
wilbur2:wilbur.asd.
- S-HTTP-Client by Sven Van Caekenberghe
http://homepage.mac.com/svc/s-http-client/
is used for s-http-client:do-http-request
Alternatively, CL-HTTP (http://www.cl-http.org:8001/cl-http/)
or AllegroServe (http://allegroserve.sourceforge.net/) could
be used (see ontolisp:http-stream.lisp)
- the other included systems (puri, s-utils, s-sysdeps, s-base64)
are required by S-HTTP-Client and are included here for
convenience (if you don't use S-HTTP-CLIENT, these directories
can be deleted)
- the ontolisp:test; library contains (original and modified version) of
the OWL 2 primer in different syntaxes for testing purposes,
http://www.w3.org/TR/owl2-primer/
as well as the famous people & pets ontology in functional syntax
by Sean Bechhofer . These ontologies are public and can be found
in various ontology repositories on the web, e.g.,
http://owl.cs.manchester.ac.uk/repository/
In order to load OntoLisp, simply evaluate
(load "/home/<yourhomedir>/ontolisp/ontolisp.lisp")
Please note that "~" will not work under SBCL, and evaluating the
ontolisp.lisp buffer from emacs will not work - the file has to be
loaded, due to the utilized *load-pathname*. If loading doesn't work
for you, simply edit ontolisp.lisp (at the position of the break).
Sourcecode / API documentation is currently not provided. Please work
through the provided examples in order to see what OntoLisp can do for
you. Start inspecting ontolisp:owlapi-test.lisp and evaluate
(owlapi::owlapi-test)
in your Listener to become familiar with the OWLAPI of OntoLisp.
Then, to learn about the OWL 2 parsing and rendering facilities as
well as the OWLlink processor and converter, inspect
ontolisp:owl-syntaxes-test.lisp and evaluate
(owl-syntaxes::owl-syntaxes-test)
in your Listener.
Please note that OntoLisp currently does not come with a DL reasoner
and hence cannot really perform reasoning. Rather. a set of dummy
functions is provided as the bridge to the reasoner which produce some
output. I will add a DL reasoner in a future version of OntoLisp.
Hence, the framework currently only addresses the syntactic aspects /
management of OWL 2 and OWL ontologies. It is rather straight-forward
to connect OntoLisp to an existing KRSS-compliant DL reasoner. Please
consult the file ontolisp:dummy-functions.lisp. These bridge functions
have to be implemented in order to attach a real DL reasoner to
OntoLisp. For illustration purposes, I have provided the reasoner
bridge implementation of RacerPro with the files
ontolisp:reasoner-bridge-for-owlapi.lisp and
ontolisp:owllink-reasoner-bridge.lisp. Of course, this can only give
you some hints on how these functions would look like for a different
KRSS-compliant reasoner.
OntoLisp was designed in a way to depend as less as possible on
third-party libraries. Consequently, aspects like URI representation
and handling may seem impoverished int he code, compared to, say,
PURI. Also the OWL 2 functional parsers etc. are hand written. But I
prefer to have things under my control and work out things for myself
rather than relying / depending on some library that I don't fully
understand. I would argue that the provided solutions are "good
enough" for what OntoLisp is trying to do, but of course, things could
be improved quite a bit. Still I hope the library contains useful
functionality and code fragments to get your OWL 2 or OWLlink project
started. The provided examples should give some hints and contain more
explanations on how to go on. Otherwise drop me a mail if you have
specific questions / problems.
Future plans:
- add OWL 2 RDF parser using Wilbur2
- add the MiDeLoRa DL system
